The evaluation research of the risk of dust pollution spread from crematorium by applying ENVIMAP 3.0 model

Abstract

There have been many pieces research on dust emissions, but the research on dust emissions from crematoriums is a new issue. The objective of this research is to calculate the dust dispersion from crematoriums into the environment, thereby determining the range of pollution and predicting the dust spread by applying the Envimap 3.0 model. The result is calculated in 2 cases, one case when the waste dust treatment system operates stably with the efficiency of 90-95% and another case where the waste dust treatment system has issues. In case of having an incident that is 2 km far from the bottom of the chimney, all objects are affected, especially, the distance is 100-700 m in winter and 100-800 m in summer. In case the dust treatment system operates stably, the concentrations of pollutants at all distances are within the allowable limits according to the regulations. The research contributes to providing a scientific basis for managers on areas affected by waste sources from crematoriums to develop an environmental protection plan to limit adverse impacts.
